I just instaled BKR5EIX-11, the car drives great on standard boost 6 but when you want boost it up to 10-12....major misfire.
I looked at my coils, they are all fine. Infact they look new. No cracks. I did notice they had white discoloration on the side, dust like. very tiny amount....
So what do I do, I had the coper sparkies gaped to 0.8 same misfire. When I bought the car 2 yeras ago, it had resistor sparkies copers aswell. The car ran 18psi no probs, 265Hp@rw...
I dont have that same power anymore.....
